    I think this is a relic. but a not sure.

    As there is no infrared source here and the radio emission is rather tightly constrained, I would say this is and #IFRS or infrared faint radio source.

    @lucasibiapino for the relic I would expect the radio source to be diffuse, you know, more irregular, this one looks like a fairly compact radio source, so we simply can't tell what exactly this is apart from #IFRS as 42jkb says. I def would not use relic here.

    Oh right, #relics are based on radio morphology and mean that the radio emission is old and associated with something that happened before, but they are not defined as those radio sources that do not seem to have host galaxy in IR. The latter are #IFRS. Soes it make sense?
